HD 1461 is a star in the equatorial constellation of Cetus, near the western constellation border with Aquarius. It has the Gould designation 32 G. Ceti,[9] while HD 1461 is the Henry Draper Catalogue identifier. This object has a yellow hue and is a challenge to view with the naked eye, having an apparent visual magnitude of 6.47.[3] The star is located at a distance of 76.5 light-years (23.5 parsecs) from the Sun based on parallax,[2] but is drifting closer with a radial velocity of −10 km/s.[3]

This object is a G-type main-sequence star with a stellar classification of G3VFe0.5,[4] where the suffix notation indicates a mild overabundance of iron. It is roughly two[6] billion years old and is spinning with a projected rotational velocity of 5 km/s.[8] This is a solar-type star with 5% greater mass compared to the Sun and 1.24 times the Sun's radius. The star is radiating 1.19[7] times the luminosity of the Sun from its photosphere at an effective temperature of 5,386 K.[7]
